For pleural effusion, BL and EP tumor cells had higher expression of mitochondria-associated genes, such as CO (cytochrome C oxidase), ND (NADH dehydrogenase), and ATP6 (Fig. 2F and Table S2), while LP cells expressed EMT-associated genes, such as YEATS4, MDM2, and RGS5 (Fig. 2G and Table S2). This evidence concerns the gene MT-ATP6 and neoplasm.
